The laparoscopic sleeve gastrectomy is considered a restrictive operation; however it also combines some of the metabolic advantages of the gastric bypass and biliary pancreatic diversion. Generally it appears to be best reserved as a standalone weight loss surgical procedure for patients whose BMI is less than 50.
In appropriately selected patients the excess weight loss with vertical sleeve gastrectomy is approximately 60-65 percent of the excess weight. The sleeve gastrectomy also has been used as the first step in a staged operation for patients with BMI greater than 50.
This procedure is performed solely on the stomach with no rerouting of the intestines. It has also been called Partial Gastrectomy, Vertical Sleeve Gastrectomy, and Gastric Sleeve. It basically consists of making a stomach look like a long tube; therefore the name “sleeve.”
In the procedure, two-thirds of the stomach is removed, which provides for quicker satiety (sense of fullness) and decreased appetite. The smaller stomach pouch restricts food intake by allowing only a small amount of food (3-4 ounces) to be eaten at one time.
After separation of the stomach into a smaller tube, the remainder of the stomach is removed. The pyloric valve at the outlet of the stomach remains; this provides for the normal process of stomach emptying to continue which allows for feeling full. Vomiting or discomfort can occur of you eat too quickly, take large bites of food, drink fluids with meals/snacks, or eat dry, tough or sticky foods.
After surgery, an average meal should be one cup of food or less over the course of 30 minutes four to five times daily spaced 3-4 hours apart. Average weight loss depends on several factors, the most important being the patient’s compliance to their new diet. Other factors include the weight a patient started at, incorporating exercise and being more active, avoiding calorie-laden beverages and complying with medical therapy for other ailments.
